Scoring methodology
Sabik, formally designated Eta Ophiuchi, is a binary star system and the second-brightest star in the constellation Ophiuchus. The system is located approximately 88 light-years from Earth and consists of two white A-type main-sequence stars. These two stars orbit each other with an estimated period...
Why this score
Bright Ophiuchus binary, respectable observational target, but limited distinctive consensus stature.
Scoring methodology
Algorab, designated Delta Corvi, is a white main-sequence star located approximately 87 light-years from Earth in the constellation Corvus. It is the third-brightest star in Corvus and is recognized as a binary star system, having a fainter companion star. The name Algorab is derived from Arabic and...
Why this score

Scoring methodology
Ascella, designated Zeta Sagittarii, is a binary star system located in the constellation Sagittarius. It is one of the brighter members of the prominent Teapot asterism, marking the lower southern edge of the formation. The system's primary star is a white main-sequence star, accompanied by a faint...
Why this score
Teapot member and binary, good constellation-marker status but moderate wider reputation.
Scoring methodology
Abell 65 is a faint bipolar planetary nebula located in the constellation Sagittarius. It is highly notable for its elongated, ring-like structure and for containing a close binary central star system at its core. The two stars in this system orbit each other with an exceptionally short period of ap...
Why this score
Close binary nucleus and bipolar shell offer meaningful research value, but extreme faintness and modest visual detail limit wider appreciation.
Scoring methodology
Xamidimura, designated as Mu¹ Scorpii, is a binary star system located in the southern constellation of Scorpius. It consists of two hot, blue B-type stars orbiting so closely that they appear as a single point of light, detectable primarily as a spectroscopic binary. The star's official name was fo...
Why this score
IAU Xhosa-named Scorpius binary, culturally notable naming but moderate astronomical prominence.
Scoring methodology
Muscida is the proper name of Omicron Ursae Majoris, a star system in the northern constellation Ursa Major. In traditional depictions of the Great Bear, it marks the animal's nose or muzzle, and its Latin-derived name likewise refers to the muzzle. The system lies roughly 180 light-years from Earth...
Why this score
Named Ursa Major giant, traditional figure marker with limited broad significance.
Scoring methodology
ι Virginis (Syrma) is a white A-type main-sequence star in Virgo, located about 69 light-years from Earth, formally named by the IAU in 2016.
Why this score
Named Virgo A-type star, visible but modest scientific and cultural prominence.
Scoring methodology
Furud is the proper name of Zeta Canis Majoris, a star system in the constellation Canis Major. Its visible primary is a hot, blue-white B-type main-sequence star, and spectroscopic observations show that the system is binary even though its components cannot ordinarily be separated visually. The In...
Why this score
Named Canis Major binary, visible but low distinctiveness among brighter neighboring stars.
Scoring methodology
Alchiba is the IAU-approved proper name of Alpha Corvi, a star in the constellation Corvus. Despite the alpha designation, it is the faintest of the five principal stars traditionally used to outline the constellation. Alchiba is an F-type main-sequence star approximately 48 light-years from Earth,...
Why this score
Alpha-designated but faint Corvus star, modest visibility and limited reputation.
